Abstract: paper studies the impacts of public health insurance on labor force participation and incomeThe theoretical model decomposes the total effect of a change in the health service charge into a substitution effect and a wealth effectThe two effects take the opposite signsWhen the substitution effect is greater than the wealth effect,an individual prefers to substitute health care with leisure time by participating more in the labor force to increase income and then to purchase better health insuranceWe use the data from China to test the theoretical findingsEmpirical results illustrate that the substitution effect in China is greater than the wealth effectA possible reason is that the public health insurance system in China dictates barriers across different insurance schemes according to household registration types or occupationsIndividuals are not able to move freely between different insurance schemes through participating in the labor forces or increasing labor supply
Key words: health insurance , income gap , labor force participation
摘要: 本文从健康资本的角度讨论了医疗保险对不同类型劳动者就业和收入的影响机制。通过构建理论模型,笔者将医疗服务价格变化造成的影响分解为替代效应和财富效应。分析发现,当替代效应的绝对值大于财富效应的绝对值时,劳动者更倾向于使用增加休闲时间进行保健的方法对健康资本进行生产,而不是通过积极就业增加收入以购买更好的医疗保险的方式。笔者使用中国观测数据对理论模型进行实证检验后发现,当受到疾病冲击时,享受城镇职工、城镇居民和新农合医疗保险的劳动者就业率和收入均呈明显下降趋势。这一发现说明,休闲时间和医疗服务在这些劳动者之间的替代效应可能大于由医疗服务价格变动所带来的财富效应。究其原因,可能是由于中国医疗保险制度壁垒是根据户籍或职业特点而设定,劳动者通过参加工作或者增加劳动时间提高收入的途径并不能帮助劳动者在不同的医疗保险之间进行自由转移,所以劳动者并不寄希望通过提高收入以寻求更好的医疗保险来购买医疗服务的方式进行健康资本生产。
